p IMRROVEIMENTIN CONSTRUCTIN 0F 'VVEISSIILS4 The Schedule referred to. in these Letters Patent and making part of the same.

. Beit known that I,"WILLIAM A. FARLEY, of-

` Andrews Bay, in the county'of Washington, and State pf Florida., have Ainvented a new .and useful Improvement in Construction of Vessels; and I do hereby declare `that the following is a full, clear, and exact description thereof', which will enable others skilled in the art to make and use the same, reference being 'had tothe accompanying drawings, formingpart of this specification. y p

The object of this invention is to provide anewand improved mode of laying out and ascertaining the form for the hulls of vessels.

The invention consists in producing-patterns of two differents curves, taken from two radii, the one ohtained by taking two-thirds the measurement of' the beam of the requiredvessel, andthe otherfrom a radius of vone-half the said measurement.' n l Also, in the use of the saidpatterns, in a manner to obtain the required curves for any part of the sides and bottom ofthe vessel by one pattern, all as hereinafter more fully specified.

Figure 1 represents a diagram of a vessel, ofthe form which it is designed to produce, and

Figure 2 represents a rear and sectionalview, showing also the application of the pattern to different parts ofthe hull. V t

Similar' letters of reference indicate corresponding parts.

I first make a diagram oi',` the plan of. the vessel I propose tobnild, and divide the line of the cross-section'at the `widest part, as at a., into thirds, and take two-thirds the distance as a radius, to form the curve of that part of the pattern for the large circle for the iloor-timbe`rs, running ouefthird the width of the vesp sel from the keel. lI then take one-third the said distance as a radius for thesmall circle, for the distance from the end of theflarge circle up to the gunwale.

In iig. 2, b represents the radial line for the large circle from the centre, distant two-thirds the breadth,

at the line a; c'and d, the radius of the small circle from the centre, one-third the said distance.

Taking these two circles so formed and united, I y

make a pattern, A, which, used as represented in iig. 2, gives the shape required at any required point along the sides of the vessel. That is to say, the lower end of the pattern being always taken for the' line of the ,keel,`the timbers for any section cut by the pattern, beginning at the lower endthereof, and extending along the pattern as much as required for the distance lfrom thekeel to the gunwale, WilLbe the shape required.

For deeper or shallower vessels, the lengths of the radii may be lengthened' or shortened, as required. Forinstance, if a light-draught vessel is required, the

Hoor-circle willbe enlarged, and the nuckel-circle willv -be shortened, and vice fee/rsu.

The same pattern reversed on the tiniber, turns the counterwork-to make the stern.

Having thusdescribed my invention,

r I claim as new, and desire-to secure by Letters Patent- 'Ihe herein-described mode of producing patterns for shaping the -timbers of vessels, substantially as specified. V

Also, the improved'mode of producing the form required for the vessel, vat any part, by means of the improved pattern herein shown and described.

The above specification of my inventionsigned by me, this 14th day of June, 1869.
